帝国CMS 列表模板list.var支持程序代码，cmslist.var

1、增加模板时list.var模板需要勾选“使用程序代码”选项。如图：

2、直接添加PHP代码，不需要加程序开始和结束标记。

3、字段值数组变量为$r，对应的字段变量为$r[字段名]，如：标题字段变量就是$r[title]。另外编号变量为$no

4、将最终模板内容赋给$listtemp变量。

例子1：如果信息没有设置标题图片就显示指定的图片。

https://www.gxlcms.com/1 https://www.gxlcms.com/if(empty($r[titlepic]))
https://www.gxlcms.com/2 https://www.gxlcms.com/{
https://www.gxlcms.com/3 https://www.gxlcms.com/        $r[titlepic]='/images/img.gif';
https://www.gxlcms.com/4 https://www.gxlcms.com/}
https://www.gxlcms.com/5 $listtemp='https://www.gxlcms.com/<https://www.gxlcms.com/lihttps://www.gxlcms.com/><https://www.gxlcms.com/a https://www.gxlcms.com/hrefhttps://www.gxlcms.com/="[!--titleurl--]"https://www.gxlcms.com/><https://www.gxlcms.com/img https://www.gxlcms.com/srchttps://www.gxlcms.com/="[!--titlepic--]"https://www.gxlcms.com/>https://www.gxlcms.com/ahttps://www.gxlcms.com/>https://www.gxlcms.com/lihttps://www.gxlcms.com/>';

说明：$r[titlepic]为标题图片字段变量。$listtemp为模板内容变量。

例子2：如果信息是今天发布的就显示“NEW”图片标识。

https://www.gxlcms.com/1 https://www.gxlcms.com/$newimg='';
https://www.gxlcms.com/2 if(time()-$r[newstime]https://www.gxlcms.com/<https://www.gxlcms.com/=1https://www.gxlcms.com/*24*3600)
https://www.gxlcms.com/3 https://www.gxlcms.com/{
https://www.gxlcms.com/4 https://www.gxlcms.com/        $newimghttps://www.gxlcms.com/='https://www.gxlcms.com/srchttps://www.gxlcms.com/="NEW图片地址"https://www.gxlcms.com/ borderhttps://www.gxlcms.com/="0"https://www.gxlcms.com/>https://www.gxlcms.com/';
https://www.gxlcms.com/5 https://www.gxlcms.com/}
https://www.gxlcms.com/6 $listtemp='https://www.gxlcms.com/<https://www.gxlcms.com/lihttps://www.gxlcms.com/><https://www.gxlcms.com/a https://www.gxlcms.com/hrefhttps://www.gxlcms.com/="[!--titleurl--]"https://www.gxlcms.com/>[!--title--]https://www.gxlcms.com/https://www.gxlcms.com/ahttps://www.gxlcms.com/> '.$newimg.'https://www.gxlcms.com/https://www.gxlcms.com/lihttps://www.gxlcms.com/>';

说明：$r[newstime]为发布时间字段变量。$listtemp为模板内容变量。

例子3：调用投稿用户的公司名称。

https://www.gxlcms.com/1 https://www.gxlcms.com/$userr=$empire->fetch1("select company from {$dbtbpre}enewsmemberadd where userid='$r[userid]' limit 1");
https://www.gxlcms.com/2 $listtemp='https://www.gxlcms.com/<https://www.gxlcms.com/lihttps://www.gxlcms.com/><https://www.gxlcms.com/a https://www.gxlcms.com/hrefhttps://www.gxlcms.com/="[!--titleurl--]"https://www.gxlcms.com/>[!--title--]https://www.gxlcms.com/https://www.gxlcms.com/ahttps://www.gxlcms.com/> https://www.gxlcms.com/<https://www.gxlcms.com/spanhttps://www.gxlcms.com/>公司名称：'.$userr[company].'https://www.gxlcms.com/https://www.gxlcms.com/spanhttps://www.gxlcms.com/>https://www.gxlcms.com/lihttps://www.gxlcms.com/>';

说明：$r[userid]为发布者用户ID字段变量。$listtemp为模板内容变量。

https://www.gxlcms.com/其他说明：
如果$listtemp引用模板内容是用单引号，那么里面使用单引号前面要加\，例如：$listtemp='\'[!--titlepic--]https://www.gxlcms.com/\'>';
相反如果引用模板内容是用双引号，那么里面使用双引号前面也要加\，例如：$listtemp="\"[!--titlepic--]https://www.gxlcms.com/\">";
